摘要
研究设计了一种新型的微力测量装置,能够测量在水面运动的微小水生昆虫腿部由于毛细效应而产生的水面浮力,并以蚊子腿为例测量了其水面浮力,从而对该装置的测量精度和测量方法进行了实验和理论验证。该装置测量微力的量程为1~2000μN,精度为0.1μN,并且能够精确地控制和改变待测物体与水面接触的速度和角度。该测量装置和方法也能直接应用于仿生水面微型机器人的腿部浮力、微液滴黏附力等一些微小表面力的测量,具有较好的应用前景。并且,本装置的设计与研发也为新型微流体器件、微型传感器等相关装置的设计制作提供了一定的灵感。
This paper designed a new force measuring device,which can be used to measure the watersupporting force of the small aquatic insects.Taking the mosquito leg as example,its surface buoyancy is measured by this measuring device,thus the accuracy of this device and method is verified through the experimental and theoretical analysis.The measuring range of this system is1~2000μN,the accuracy is0.1μN.And the system can precisely control and change the contact speed and angle of the measuring object.The measuring device and method can be directly applied to measure other small surface force,such as the water-supporting force of the bionic water-surface robot,the adhesion force of micro droplet and so on.Therefore,this device has a good application prospect.In addition,the design and development of this device is also designed for the new microfluidic devices,micro sensors and other related devices provide some inspiration.
